I just woke up and found your note, Jim. 

 JH> I _still_ haven't gotten around to working on these old inkjet
 JH> cartridges here.  (I'm running behind on that, too)

        Be one of the gang ! I just got back to Roxboro and have not yet
        relocated all the stuff that I brought to/from Kamouraska, tools,
        books and all kind of stuff. Oh, well !

 JH> If I fail with the distilled/isopropyl, I'll surely give ammonia a
 JH> try. Not for too long, though, as I'd worry that the NH3 or the OH
 JH> might end up corrosive to the contacts on the ink cartridge.  rummage,
 JH> rummage - Looking at an old HP cartridge,  I'd use the ammonia in a
 JH> shallow pool, so as to contact only the inkjets on the bottom,  not the
 JH> contacts which run up the back side of the cartridge.

        Are these not gold plated and that explains their high cost ?

        On the Lexmark here, I have two carriers and one prints black
        fine and not colour, the other is the opposite. Fun ! So I am
        also looking for a solution ( pun ) to this problem of
        revitalizing a printhead. Listening......

        No HD yet.
